You might be wondering why the episodes are labeled with the number "2" at the beginning instead of "3" since it's Book 3. As mentioned by Bryan two years ago, that is because Books 1 & 2 are considered one season while Books 3 & 4 are the second season. Hence why the episode numbers from Book 3 onwards will start with 2.

It's a little confusing but here on ASN, we'll just number them according to the Book number. ;)
